Domestic sewage treatment device

Abstract

The invention discloses a domestic sewage treatment device which comprises a supporting plate, an angle adjusting mechanism is installed at the bottom of the supporting plate, a first driving mechanism is installed at the bottom of the angle adjusting mechanism, a second driving mechanism is arranged at the bottom of the first driving mechanism, and first cleaning mechanisms are installed on the two sides of the second driving mechanism. A first cleaning mechanism is mounted at the bottom of the first driving mechanism, a second cleaning mechanism is mounted at the bottom of the second driving mechanism, the first cleaning mechanism is driven by the first driving mechanism to move, rotation of the first cleaning mechanism is adjusted through the angle adjusting mechanism, and the four walls of the sedimentation tank are cleaned. The second cleaning mechanism is driven by the second driving mechanism to clean the bottom of the sedimentation tank.

Description

technical field [0001] The invention relates to a treatment device, in particular to a domestic sewage treatment device. Background technique [0002] Domestic sewage is the waste water discharged from the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infection viruses, etc.). The organic matter present in the domestic sewage is extremely unstable and easily corroded to produce foul odors. Bacteria and pathogens multiply with organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before it is discharged. [0003] The e...
